Error on second call of BAPI CustomerMaterialInfo GetList

[Mumrik]

Hi,

I always get a BAPI error message if I call the GetList-method of "CustomerMaterialInfo" for the second time (in VB). The first call is always successfull (BAPIRET2 is 'Nothing'). The second call fails with error message "Internal error processing the logical database KIV" (sorry, as I have a german SAP version, I don't know the exact error description of the US version).

Only if I do a Logoff / Logon between subsequent calls, the GetList-method works fine again.

Thanks a lot for any help!
