MRP run

Hi,

Our demand is from Sales order. After the MRP run, the Po will be issue for this product. After we get the product from the vendor we will do a good receipt, when the GR done the qty of the product will increase. But in our system, we don’t keep the product qty in SAP but in another system. So, once GR is done, it will be issue out from SAP. We are having problem here, if we issue out the product and always keep the inventory in other system, then MRP run, it will always raise an PR to create the PO because the particular product inventory is always 0. So, I was wondering if there is any field for us to input inventory qty, so that MRP can run correctly based on the qty input? Or maybe there is other work around?

hi Janice,

if I understand you correctly than.. you do the good receipt into SAP and than transfer(remove) the stock to the other external system. Now in that case mrp generating new requirement for that material.

now if it the case than you cant help it because it will surely generate the purchase/plan order when ever mrp run, you can avoid it by not running mrp for that but it will be much complicated.

the best solution would be to not to issue all the goods at once. but when you issue in external system, you simultaneously issue the qty in sap. there are no of ways by which you can achieve this. and with almost all programming language it is possible without any problems.

in short when you have stock in sap. you can display the same stock in external system and at the same time when you issue in external system it will be issue from sap.

hope this helps.

regards,

Solomon

Hello

You can use BAdI MD_CHANGE_MRP_DATA to make the sales order not relevant to MRP or to manipulate the stock quantity. See the blog with an example.

Hi Janice

MRP works with Unrestricted and Quality Stock. If you're doing GR in a non-SAP system you have two option

1. doing GR in SAP system which means double data entry by warehouse employee.

2. develop a web-service which creates SAP Material Document as soon as GR is posing in non-SAP inventory system.

Hi,

If you want MRP to exclude your material you can assign it MRP type ND.
