FM Customizing Date (FMOD) related with doc date in PO

Hi FM Experts,

I have a problem related with PO creation.

When logistic section want to input outstanding PO, the doc date in PO (tcode: ME21N) filled according to the date of PO creation.

Logistic section tried to entry the doc date 02.10.2011.

There is an error related with FM, said that Posting date/period 02.10.2011/007 is earlier than existing date/period 24.10.2011/007.

According to the error, there is one updating process in FM (FM Customizing Date) in FMOD.

I don't know yet about FM customizing date. What date I should entry in FMOD?

If I entry 02.10.2011 in FMOD, the error stills exist.

Many thanks 😊

    HI, it's because PBET is active. Seems you create PO based on PR?

    Please refer to link Invoice posting Error

    FMOD is used inly for exeptional cases, where you want to force FM date for all FM transactions. Normally, you use it during migration process.As for your error, apparently, PR FM date is 24/10, while the PO, which is a following document, should be entered with the date after the predecessor.

    What date should I entered to FMOD? Because I entry the PO date, the error still exist.

    I read another forum, there is the exit EXIT_SAPLFMFA_004. What's the function of the exit?

    • Hi Eli,

      Thanks for your reply.

      I implemented the user exit. Seems I'm still confused what date must be entry to FMOD.

      But in the client server, there are 3 company code that unrelated between each other. So I must entry the condition that the user exit only had an effect on company code I implemented, right?
