My doubt is what to fill in MRP3 view in availability check?Option 1 or Option 2?? Option 1 and option 2 both have same controls in customization! Even though it has different controls on what basis I can decide what to choose? Please tell me what to give in case of ROH, HALB and FERT individually.
Please go to transaction OVZ2.
Here you can see the definition of checking group
Hit F1 on the individual fields, you have examples in the help screens.
This will help you understand the implications of choosing any of the entries
Though the field says "Availabilty check" actually you are choosing the checking group for the material which will decide how the requirements will be transferred to Stock reqmts table during sale order / delivery processing.
Eg: If you choose 1,
There are 2 sales orders for the day with qty 10 & 20.
The system creates a line in the requirements/stock overview for each total of summarized requirements for the day ie 30 nos.
If you choose 2,
Two indivdual liness will be created in MD04 table.
This field is very much relevant for availability check because, the checking control is defined for the combination of the checking group entered in this field and the checking rule defined in customising. This checking control determines how the avblty check should be carried out.
