Scnario A resulting in document flow missing

Hello All,

We have a scnario to change Debit memo request to be chnaged in ECC.

so i have maintained a parameter in CRMPAROLTP table for Scnario A.

now i am able to change the document in ECC but the problem is, if i bill it in ECC, corresponding document flow is missing in CRM.

If i remove the parameter, i m getting doc flow.

Can anyone give me a hand pls..

Regards,

KP.
