Blocking storage locations from MRP can be useful e.g. if you wish to exclude inventory in showrooms from procurement decisions.
To block storage locations from MRP you can go to to IMG > Production >Material Requirement Planning > Planning > Define Storage Location MRP per Plant. In the plant/storage location overview set indicator ’1′ behind the location you wish to exclude from MRP.
This is a very simple configuration. However if you overlook this you may run the risk of implementing MRP areas for the same purpose, but with a lot more effort and impact.

I’m working in a business process where a sales orders requirement date should never be transferred to MRP with the original customer’s requested date.
Example: at the time of order entry ATP bounces the requested delivery date, since product is not available at the time. The system suggests a new date for confirmation. The customer at this time has the option to agree to the new proposal or a sales order will not be entered. I want this new committed date transferred to MRP.
To do this I select the ‘Fixed date and quantity’-indicator in the Schedule lines tab in VA01. As in my case this should always be the case, in customizing I choose this as a default setting for the specific SalesArea (IMG > Sales and Distribution > Basic Functions > Availability Check… > Availability Check > Availability Check with ATP… > Define Default Settings)
VA01 - Fixed date/qty indicator
Without setting the indicator you are basically suggesting that production can still catch up with this additional requirement and the customer’s original requirement date will be transferred to MRP. See also SAP Help.

At some point in time sales and delivery requirements may get out of sync due to maintenance resulting in planning errors. Usually these errors are found when going through MD04. You will typically find deliveries (collective requirements) that cannot be traced back to original delivery documents.
The proper solution for this is to run report SDRQCR21 (via SE38):
Program SDRQCR21
- select the material and plant you wish to run the correction;
- select the option data transfer when you actually wish to run the correction on the database;
- select compare always in order to improve performance. Without selecting this the whole database for material/plant will be regenerated;
- select planning entry to ensure the material is included in the next MRP run;
- the option Processing per material results in a different log.
After this your MRP overview should be back in sync.
