PI EDI help: What is the source of ISA13 in a IDOC to EDI mapping

[Former Member]

Hello Experts,

It would be of great help if you can provide the field mapping for ISA 13 in outbound from IDOC sceanrio:

IDOC: INVOIC02 - to - EDI 810 mapping.

Is it the best practice to have ECC send the value in a particular IDOC field ( like RFINT) or PI has to use a custom function to populate the ISA13 field.?

Thank you,

Patrick.

Hi,

ISA13 is for Interchange Control Number. It is a control number assigned by the interchange sender.

Normally its Sequential number starting with 000000001 and incremented by 1 for each subsequent ISA between sender and receiver.

This is a very useful value to include. It creates an explicit link between the IDoc and the EDI transmission. This number eases Production Support greatly. When there's an issue with a Partner EDI transmission, the Partner's EDI support people want to know the Interchange Control Number

The IDoc interface does not process or check this field.

Thanks Ganga,

I got the picture now.

Now to a finer question. When you say IDOC doesn't give that value, PI has to put a sequence number. What is the exact map ? Do we use counter function and then format the value to the desired number of characters.

When PI is restarted, what happens to the counter value, does it restart from 1 again. How do we persist the last sequence value before PI server is bounced. How to manage the sequence numbers in a PI cluster environment.

Thanks,

Patrick.

Hi,

Instead of trying to pass in Mapping .Search if there is any user exit for the IDOC.So that you pass some Sequential Number within UserExit Implementation.

Hi Ganga

Can you suggest any more options, apart from using the user exit.

Anything on PI side in the message mapping (or) do we have any option on the ABAP side in ECC.

Your help is greatly appreciated!!

Thank you,

Patrick.
