Issue with ADRMAS and CREMAS

Hi Experts,

I am working on File to IDoc scenario.File is splitting into CREMAS and ADRMAS.In mapping i am assigning Vendor number to ADRMAS idoc also.Idocs are recieving at SAP ECC system and posting succesfully.

But issue is both idocs are creating different ADDR number,so that data in both idocs not correlating each other.

I am processing first ADRMAS and then CREMAS.

If i am testing from WE19 it's working fine.Both idocs creating same Addr number.But the problem is with IDocs coming from XI.

Could u please suggest me to resolve this issue??

Regards,
