Hi Kumar

Program Name: RMMRP000

Variant : you can keep "MRP Plant 9030" as variant name

For frequency and Timings, you can select the variant and go to the Schedule button. There you can make settings for frequency as well as time.

You can create this background job either in MDBT or SM36 transactions.

Planning mode as 1 is enough. If in your business context BOM / Routing keeps changing often, then depending on the frequency of change you might want to consider having a weekly or a monthly MRP job with planning mode as 2. As regards to planning mode 3, it is seldom ever required, unless you for some reason want to delete the entire planning data & re-create them back.

Hope it clarifies.

Hi,

As Vivek said, planning mode 3is used to delete the entire planning data & re-create newly. This is the impact of Planning mode 3.

Hi Vivek,

Thnks for your input,Now i have created and scheduled the batchjob in Qulaity please let me know what are the parameters now i need to check in Quality like job is running fine or not .....

Check the runtime of the job, should be within the defined limits for background jobs defined by basis people. Also ensure the job completes successfully, if not check the reason for termination.

The above are just basis checks, you can ask your basis people to help you with it. From a MRP job perspective, check if there any group-8 messages i.e. termination, if there is check & correct the reason for the same. Also execute MD21 report to see if any material still has a flag for MRP (note this check you do immediately after MRP run & if there is a flag check MD05). Also analyze the results via MD06.

The above should give you a fair idea about the outcome of the MRP run, the remaining needs to be checked & analyzed by the respective MRP controllers.

HI Vivek,

Thanks once again for your valuable inputs.Will check the same with users / MRP controlers and revert back with my inputs.

But the problem is I have scheduled the batchjob at 1 CET in night so i could not check immmedaitely after MRP run any other alternative inputs from you.

The checking of planning file is just as a check n balance kind of approach, its not like you have to do it.

Anyway the key things to verify would be the background job nor the MRP run for any material terminates. Since you say it is the first time you're doing it, you may ask your basis person to include your email id in the job, so that you can get a spool (check with your basis person for this).

Hi vivek,

I have checkd in SM37 and observed that batchjob has finished sucessfully within time limitis.

As you said today i have checked the termination messages in Md05 for two materails and observed that two materails MRP type is related to APO hence i think this could not be an issue.Please comment on this.

Also i have executed MD21 after MRP run and couldnt track the MRP flag activation what you are refering for the two materials whihc is apperaring in MD21.Request you to comment on this also.

Cheers,

In MD05 for the materials which have a termination system would let you know the reason as to why it has terminated, so analyze the same & it will be clear.

As regards to MD21, you should notice that the planning file entry for those 2 materials which are terminated are not cleared, meaning the next MRP run will try to plan these materials.

Anyway the above are the tasks of the MRP controller.

HI Vivek,

i observed today that yesterday MRP run batchjob has taken too much of time ie, it is not with in time limits.How to analyze this case please suggest.

Also tell me in genrela if any batchjob not run with in time limits wat are all the check i need to perfrom.

Cheers,

For the job which you refer to, go to the spool & study the section 'Runtime statistics'. It will let you know which section took how much time & based on that you would be able to infer what has caused the delay & thereby take suitable actions.

Also note, there is no generic rules as such, each case has to be analyzed if there is a delay. But in general it is better to ensure your planning file entries are consistent, processing key - NETPL or NETCH & planning mode is 1.

I guess this thread has gone way beyond the initial posting, so for any further analysis on this MRP job I would strongly suggest that you sit down with the MRP controller & analyze the same. I am quite sure it shouldn't be difficult in interpreting the results.

Good luck.
