Source of supply is not selected when using a special procurement:Ģ3035 No vendor from source list during spec. This is the standard logic and the selection of a valid source of supply for MRP should be based on the 'Source List Usage in Materials Planning' indicator, which is highlighted on the previous source list figure.ġ10074 MRP: Source of supply, several valid source list records The fixed source of supply indicator is not considered by MRP. info: Validity source list/quota arrangement for MRP ' Fixed source of supply' indicator is not considered: The following note provides more details about the system behavior:ġ09380 - Add. That's because it was generated to cover a requirement from, which is outside the source list validity. Here, even though the first purchase requisition is within the source list validity, the vendor was not selected. Therefore, if there is a rescheduling message with a date pointing to a period outside of the source list validity, the source of supply will not be selected.įor example, considering the source list from the previous screenshot, we have the following MRP results: The source list validity is checked against the requirement date, not against the date of the replenishment proposal. The source list is checked in order to decide which sources of supply are valid and should be considered by MRP during the source determination.Ī source list is created on transaction ME01 and the source of supply it will only be considered by MRP is the proper value is set for the field 'Source List Usage in Materials Planning', as shown on the picture below:įrequent issues on the source determination using a source list: Problems with the source list validity: The most simple way to activate the source determination during the MRP run is using a source list. The info record can be created on transaction ME11 and it is very important to ensure that the information from the tab Purchasing Organization Data 1 is completed. The existence of an info record is not enough to allow the selection of the vendor by MRP, however, without an info record we cannot create a source list or a quota arrangement, which are the basis for the source determination. The creation of the info record tells the system that a specific material can be supplied by a vendor and it contains relevant MRP information, such as the planned delivery time. The creation of the info record is a basic pre-requisite to activate the source determination during the MRP run.

The information from this WIKI is not relevant for S/4 HANA, since the source determination logic was simplified.
