No commitment item entered in item 002

Hi,

We have activated the BCS part of FM, and while posting the entry through MIR4, following is the error.

"No commitment item entered in item 002...." This item pertains to GR/Ir clearing account.

In one of the thread the solution given is "using the FLG_SES_OVERWRITE flag in the FM01X table" . In this case do  I need to maintain the same in view directly in production?

Is there any other solution?

Please guide.
