Dear SAP Experts,
I want to make such changes that in CO02 , in read PP master data tab, user cannot enter past date of BOM explosion date and Routing Explosion date. User can enter only today date. How can I restrict through standard.Thanks
Regards
Muhammad Umar
Hello,
Please check the below link that describes checks in Read PP master data:
http://scn.sap.com/thread/3379891
May be useful, I have not used/implemented this kind of checks till date.

Hi Muhammad,
In my opinion, No.
The default explosion date is determined by the system as explained earlier by expert Mangal from the citation of the SAP help. I would suggest you to consult OSS note 506345. It discusses the details of setting V_T399D_S - BESAL value (accessible through SM30 transaction), alternatively OPPQ -> BOM explosion for the plant.
I agree with expert Jaganmohan's response.
I feel you need to implement something custom (enhancement/ BAdI etc.) to achieve your requirement. Please also check BAdI WORKORDER_UPDATE method AT_SAVE to generate error message during order save, if the explosion date fails your custom check.
Best Regards,

Dear Umar,
Check this for determining the BOM explosion date,
If the production order is generated by converting a planned order then the explosion date is copied from the planned order.
If the production order is added manually the system determines the explosion date as follows:

If you have specified in Customizing for material requirements planning (plant parameters) that the explosion date is to be at the end of the order (bill of material explosion) then the system uses the same procedure: If the order finish date is specified, then this is copied. If no order finish date is specified then the explosion date is determined using the in-house production time.

If scheduled dates are specified instead of basic dates then the system calculates temporary basic dates by taking the relevant order floats (floats before and after production) into account.

In this case do not maintain any values in the field Start in Part in T.Code OPU3 for the production
order type and plant combination,so in this case if the start date lies in the past the system
automatically carries out Today Scheduling. In this case the BOM explosion date cannot be in the
past.
Also check this link to understand the read PP Master data concept,
Criteria for a Single Order
Various checks are carried out when reading a new routing or BOM in a single order.
Reading a New Routing
If one of the following questions is answered with yes then a new routing cannot be read in:
Reading a New BOM
If one of the following questions is answered with yes then a new BOM cannot be read in:
