File Merge in BPM?

Hello Everyone,

We are on SAP PO 7.4 single stack.

As part of a requirement, we have to do file merge (of files coming from multiple sources) in BPM and send it back to PI.

For example:

• We have File1 [X number of fields.. field1, field2, field3] being picked from legacy_system_1 by PI and sent to BPM
• After 30mins (lets say), we have File2 [Y number of fields.. field1, field4, field5] being picked from legacy_system_2 by PI and sent to BPM
• BPM does the merging part. The output file should have 5 fields [field1, field2, ...field5] and sent back to PI

I know this can be done in BPM via writing a custom EJB function. But, I want to know if there is a standard way to do file merge in BPM (not ccBPM). Probably a standard (FileMerge) pattern that can be leveraged?

Thanks,

Sai
