We have to submit program 'RCUUPDMATVAR' for updating all standard tables

( T-Code : CUUPDMV ) .

If we dont use it, you can see correct value on Material MRP3 view ( MM03/MM02) but

some table hasnt updated correctly.

We should create a background job with some delay. Because, FM MATERIAL_SAVE_CONFIGURATION is locking material master with some time.

Without delay, program is giving lock material error.

With this idea, I created a FM 'ZKRZ_FM_UPDATE_MAT_CONF_JOB'

FUNCTION zkrz_fm_update_mat_conf_job.
