Impact for adding new feilds in IDOC on SAP PI interfaces.

Hi Experts,

I am working on a issue in which changes are required in a IDOC (Custom) which is integrated to receiver side VIA SAP PI.

Idoc is used by many different SWCV.

If i do the changes in existing IDOC will it impact on the other mapping.

If yes what is the alternative for adding the new requirement in IDOC.

If No then why it is not impacting.

Experts please advice.
