tks for your help,
but i had just done it. I explain with detail my step:
I add the customer field at subscreen of purchase requisition by
EXIT_SAPLMEREQ_001 and EXIT_SAPLMEREQ_002 and EXIT_SAPLMEREQ_003 (at
the data base table I add the relative field on ci_ebandb include).
I add the same customer field at subscreen of purchase order by
EXIT_SAPMM06E_016 and EXIT_SAPMM06E_017 and EXIT_SAPMM06E_018 (at
the data base table i add the relative field on ci_ekpodb include).
Step followed:
1. add field at EBAN table by CI_EBANDB include
2. add same field at EKPO table by CI_EKPODB include.
3. write code at EXIT_SAPLMEREQ_001,EXIT_SAPLMEREQ_003 following
document's help.
4. write code at EXIT_SAPMM06E_016, EXIT_SAPMM06E_017 ,
EXIT_SAPMM06E_018 following document's help.
5. build dynpro 0111 on function group XM02
6. build dynpro 0111 on function group XM06
The problem is: when i convert the purchase requisition in purchase
order (ME59n), the data into customer fields of purchase requisition
not are copied in the customer fields of purchase order (this field are
empty).
Tks for your help!
