Hi Larry,
Do like this.
In target DSO DTP(DSO2-->Target DSO), for "Account document number" write routine as like below.
- Read account document number from DSO2 for G/L 400000 - 499999 (which already you know from DSO1) for company code, account doc type, fisvarnt, and fiscper
- By implementing in DTP with above logic you can get only account numbers which are related G/L account 400000 - 499999 in such way you may restrict , first check manually and if you feel comfortable then do code in DTP.
Thank you,
Nanda
