MASS transaction - Customer master update - field not a valid input field

Hello Everyone,

We are trying to use the MASS transaction to block a large number of customer records at one go. However, we are facing an error when we do it on the production environment.

The system returns an informational message, "Field KNA1-FAKSD is not a valid input field," and the blocks are not updated to the master record.

However, the same transaction works without any message successfully on our quality environment.

The user role authorizations are similar on both environments.

The long text provides the following information:

Diagnosis

A transaction is processed using batch input.

System Response

The runtime error field xxx occurs (invalid entries)

Procedure

Correct the batch input data. Depending on the processing scenario, this can
affect either of the following objects:

Batch input session
CATT
procedure
Application program

Does this mean we have to use CATT or LSMW or is there some other authorization issue ?

Has any of you faced such an issue and if so could you please let me know the resolution?

Cheers,

MRI
