how to add multiple entries to A/P batch?

No, you compose once, then make your loops.

Thank you for response, but problem still exists.
Task: insert into A/P batch a new batch record, and multiple entries each with a single details record.
What I'm doing:

usual compositions, than:
ap0020.CNTBTCH.PutWithoutVerification(0);
ap0020.RecordClear();
ap0020.RecordGenerate(true);
ap0020.BTCHDESC.Value = batchDescription;
ap0020.Update();

foreach (CheckLineItem lineItem in file.LineItems)
{
//ap0021.CNTITEM.PutWithoutVerification(0);
//ap0021.RecordClear();
//ap0021.RecordGenerate(true);
ap0021.RecordCreate(ViewRecordCreate.DelayKey);

ap0021.IDVEND.Value = file.VendorCode;
ap0021.PROCESSCMD.PutWithoutVerification(7);
ap0021.INVCDESC.Value = lineItem.CaseFileNumber;
ap0021.Process();


ap0021.IDINVC.Value = lineItem.VendorInvoiceNumber;
// on next iteration I'm getting Accpac error here (after
// very long delay it returns from API call):
// Invoice
// Invalid field index: 999999993.

ap0021.AMTGROSTOT.Value = lineItem.Amount;
ap0021.DATEINVC.Value = lineItem.InvoiceDate;
ap0021.ORDRNBR.Value = lineItem.CaseFileNumber;
ap0021.INVCDESC.Value = lineItem.CaseFileNumber;

//ap0022.RecordGenerate(false);
//ap0022.CNTLINE.PutWithoutVerification(0);
ap0022.RecordCreate(ViewRecordCreate.DelayKey);

ap0022.IDDIST.Value = lineItem.BillingCode;
ap0022.AMTDIST.Value = lineItem.Amount;
ap0022.IDGLACCT.Value = lineItem.BillingCode;
ap0022.TAXCLASS1.Value = 1;

ap0022.Insert();

ap0021.Insert();

}

strange, but everything works well with a single cycle iteration, and error appears only on the second step...

I doubt, I skip somewhere something like
APINVOICE3detail1Fields("CNTLINE").PutWithoutVerification ("-1")
APINVOICE3detail1.Read
but I'm not sure where...

Please ignore strange syntax used above to access fields/views, I'm using my own library for convenience.

Do you know where could be a problem?

Here's a VBA snippet that runs flawlessly:

ApInvoiceHeader.RecordClear
ApInvoiceHeader.RecordGenerate False

ApInvoiceHeader.Fields("IDVEND") = recDetail.Fields(D_vendorId)
ApInvoiceHeader.Fields("DATEINVC").PutWithoutVerification (MakeDate(recOrder.Fields(H_creationTime)))
ApInvoiceHeader.Fields("IDINVC").PutWithoutVerification (recOrder.Fields(D_transactionId))
ApInvoiceHeader.Fields("DATEDUE") = GetTermsDate(recDetail.Fields(D_vendorId), MakeDate(recOrder.Fields(H_CheckInDate)), MakeDate(recOrder.Fields(H_CheckOutDate)), ApInvoiceHeader.Fields("DATEDUE"), ApInvoiceHeader.Fields("DATEINVC"))

AddAllAPHeaderOptionals recOrder, recDetail

Do While Not recDetail.EOF
If Val(recDetail.Fields(D_extendedCost)) <> 0 Then

ApInvoiceDetail1.GoBottom
iLine = ApInvoiceDetail1.Fields("CNTLINE")
ApInvoiceDetail1.RecordClear
ApInvoiceDetail1.Fields("CNTLINE").PutWithoutVerification (iLine)
ApInvoiceDetail1.RecordGenerate False
ApInvoiceDetail1.Fields("IDGLACCT").Value = GetCostAccount(recDetail.Fields(D_detailType)
If recDetail.Fields(D_detailDescription) <> "" Then ApInvoiceDetail1.Fields("TEXTDESC").Value = recDetail.Fields(D_detailDescription)
ApInvoiceDetail1.Fields("AMTDIST") = Abs(recDetail.Fields(D_extendedCost))
ApInvoiceDetail1.Insert

nDetailAmount = nDetailAmount + ApInvoiceDetail1.Fields("AMTDIST")
ApInvoiceHeader.Fields("AMTGROSTOT") = ApInvoiceHeader.Fields("AMTGROSTOT") + ApInvoiceDetail1.Fields("AMTDIST")
End If
recDetail.MoveNext
Loop

Your code inserts multiple ApInvoiceDetails, but a single AP Invoice Header. I need to insert multiple Invoice Headers...

I found, that field IDINVC (which I have problems with) belongs to second composite key: Vendor Number/Document Number: ORIGCOMP, IDVEND, IDINVC - may be it is the reason?

Basically, I'm a little shocked, because it looks like there is no rules of insertion - I used protocol, described in 2007_SDK-ProgrammingGuide.pdf from Accpac site - but it doesn't work:

Insertion protocol
The following insertion protocol must be followed for views
that are classified as batch/header/detail.
1. Put zero in the batch key.
2. Init batch to get the next available key for the batch.
3. Put the fields in the batch.
4. Verify the batch. (Optional.)
5. Update batch. (The batch record is already inserted by
the Init call, in step 2.)
6. Put zero in the header key.
7. Init header to get the next available key for the header.
The key for the batch in the header view is assumed to
be set already by the composition.
8. Put the fields in the header.
9. Init detail to initialize the fields.
10. Put zero into the detail key field to insert from the start.
11. Put values in the other detail fields.
12. Verify detail. (Optional.)
13. Insert detail.
14. Go to step 11 until no more detail.
15. Verify header. (Optional.)
16. Insert header. (This will do a Post of the details.)
17. Go back to step 6 to add another header.

looks, like others used generated VBA macro files as a reference... but I'm still playing with them trying to remove garbage and make them work...

also, I've noticed, that if I change in my code line

ap0021.IDINVC.Value = lineItem.VendorInvoiceNumber;

to

ap0021.IDINVC.PutWithoutVerification(lineItem.VendorInvoiceNumber);

I will have same problems during record insertion on last ap0021.Insert(); command

OK, fine, if you want multiple invoices, you simply need another loop.

do until {whatever condition}
ApInvoiceHeader.RecordClear
ApInvoiceHeader.RecordGenerate False
{Set the header fields
{insert details}
ApInvoiceHeader.Insert
Loop

It doesn't take any fancy programming.

Code below runs perfectly one-by-one - when I run it over single line item in a file, and hangs on IDINVC assignment if I'll group two SAME line items per file (of cause I'm restoring DB backup every time):


foreach (HBCheckLineItem lineItem in file.LineItems)
{
ap0021.CNTITEM.PutWithoutVerification(0); // 6. Put zero in the header key.
ap0021.RecordClear();
ap0021.RecordGenerate(true);// 7. Init header to get the next available key for the header.
// The key for the batch in the header view is assumed to be set already by the composition.

ap0021.IDVEND.Value = file.VendorCode; // 8. Put the fields in the header.
ap0021.DATEINVC.Value = lineItem.InvoiceDate;
ap0021.IDINVC.Value = lineItem.VendorInvoiceNumber; // Document Number
ap0021.AMTGROSTOT.Value = lineItem.Amount;
ap0021.IDINVC.PutWithoutVerification(lineItem.VendorInvoiceNumber); // Document Number
ap0021.ORDRNBR.Value = lineItem.CaseFileNumber; // Order Number
ap0021.INVCDESC.Value = lineItem.CaseFileNumber; // Invoice Description

ap0022.RecordClear();
ap0022.RecordGenerate(false);// 9. Init detail to initialize the fields.
ap0022.CNTLINE.PutWithoutVerification(0);// 10. Put zero into the detail key field to insert from the start.
ap0022.IDDIST.Value = lineItem.BillingCode; // Distribution Code
ap0022.AMTDIST.Value = lineItem.Amount; // Distributed Amount
ap0022.IDGLACCT.Value = lineItem.BillingCode; // 11. Put values in the other detail fields.
ap0022.TAXCLASS1.Value = 1;
ap0022.Insert();// // 13. Insert detail

ap0021.Insert();//16. Insert header. (This will do a Post of the details.)
}

Actually, I'm doing it. Below is the generated macro code, which has no problems.
My code uses same idea: generate header, generate details, insert details, insert header - move to the next header... but why it fails on IDINVC assigment?

I know it looks stupid and annoying, sorry... Do you have skype? My ID is pavel_maltsev, I can share my screen if you have time and interested...

Looks, like there is an error somewhere in Accpac C#.NET library or so... in any case cleaned-up VB script works without any problems from Accpac, while absolutely same C# code have problems with IDINVC assignment...

Code below runs successfully on C#, it's almost direct translation from VB script. Strange, but it doesn't work if I'm using my lib with view names/fields shortcuts, which seems to work well before... May be bug is there.

Thank you, tuba, I'll try to find it myself.
