Satish,
I followed what you wrote in the thread you gave me. It didn't solve the problem.
Some other elements,
-the requirement are 111 for LPJ1 and 109 for LPH1 (I activated requirement 111 as it wasn't done in standard)
-when I send FRC and JIT releases via me84, LPH1 appears in message per release (me38) only for FRC releases and LPJ1 only for JIT releases.
-the JIT indicator is set to 1 in MM02/MRP2 for my material
-the firm period to 10 days in additional data of scheduling agreement
Activating the release creation profile just filled the next JIT release in the creation/transmission tab of release overview in me38 but didn't allow the release to be filled with release date and time of release, the 2 mandatory condition for the system to increase release number on the next release creation.
You can see:
in caption 1 the release overview table,
in caption 2 the general parameters of the creation profile,
in caption 3 the aggregation horizon,
