Can I modify the special purpose ledger table by adding a field ? will it create problem ? What precaution we need to take for this?

Thanks in advance

You can refer this help to add a field to a standard table.

But more importantly you should find how would you populate the data in that additional field.

Like, you should find a user exit in the standard program/transaction which populates the FISL table.

Dear Bonny,

It is possible to add fields to any standard table provided that the last field of the table is not a long field (data type VARC, LCHR or LRAW).

It doesn't get overwritten during an upgrades as the append structures is in the customer namespace.

Best Regards,

Guys, thank you for your response. May be I have not made it clear is that, this table is not standard but custom. This is special purpose ledger table which we create for our purpose , what I want to know is it is mapped to certain fields. When we add a field I will not be mapping it to any other field.
