Let me understand what you want to accomplish here. do you want to show the SOP distribution accounts of all the items in an invoice/order/etc?
if yes then here's what you need to do in Crystal:
1) Add tables SOP10102, GL00100. GL00100 should be added a couple of times which depends on how your Chart of Account is structured. Example, your COA is 3 segments so you'll add GL00100 to your Crystal 3X. The first one would be GL00100 then succeeding tables would be called GL00100_1,etc.
2) Link SOP10102 to every GL00100 tables by using ACTINDX then left-outer join
3) Insert 2 groups: a) SOP10102.SOPNUMBE(Document Number) b) SOP10102.ACTINDX
4) In GL00100 drag ACTNUMBR_1 to the SOP10102.ACTINDX then repeat this to GL00100_1 drag ACTNUMBR_2 to the same group. Repeat the process 'til you have all your segment.
5) Do a test run on one document then compare in Great Plains
6) If everything looks good, you can go further by creating a Formula that would show the segments in one field instead of many.
Hope this helps. Goodluck!!!
