Hi,

If there is any change related qty or date or change in MRP related, those materials are entered in MRP file. Only those materials are considered in next MRP, with net change planning or net change planning with planning horizon. If the changes are not related to MRP, Then material entry will not be done in file.

After changes related to SPRO if you want to take MRP of that material go for MD01 with processing key regenerative planning, enter plant. Those changes will be considered.

Hi,

1. The first step of MRP run is checking the planning flie entries.

The system checks to whether material is to be planned due to a change

relavant to MRP and how to proceed if there are already existing firmed

procurement proposals.

So check in tcode MD21 whether any planning file entries exists befor you run MRP.

2. NETCH indicator is entered if there is any change in reqmts qtys /dates

change to stocks

Note:

If you have changed the MRP Type / lot sizing procedure /purchasing processing time in customising the materials that are affected by these changes are not included in the planning file and thus have no planning file entry and hence we need to run the MRP WITH NEUPL Indicator.

Hi Gide,

This depends on the planning type and planning mode. Like in case of NETCH run if there are no changes were happens the materials and you have not ticked the indicator "planned also unchanges materials" in the process control parameters in MRP run then nothing will happen. Similar in NETPL if no new requirements found then there will be no change in planning.

With planning mode 1 "adjusts basic dates" system only adjusts the dates if any changes were done to the requireemnts otherwise there will be no change till you have new reuquirements.

The reasons could be many:

Some are...

1) Check Masters - have you mained PD in MRP2 view.

2) Are there requirements maintained for the material.

3) Have you activated MRP for the plant.

4) If you requirement is a sale order. What is the MRP strtegy in the MRP3 view. If 20 then if the reqmt type in sale order = KE.

Check the above and come back on the Material master settings and the requirements - sale order reqm type or PIR reqmt type.

Hi Gideon,

Does the MRP active indicator has a tick mark for the respective plant ?

Also if you want to detele & recreate planning data, set the planning mode to 3 in md01/md02 screen.

Also before mrp run, check the planning file entry (md21)
