Restriction of posting date in transaction CO11N for partial confirmations

Question

Hi all,
      I am trying to restrict(by checking thru an exit)  the posting date in co11n , for this i m using enhancement CONFPP04.
     Import parameter AFRUD_IMP IS USED.
     Now when i m putting  production order no , operation activity no.(for e.g 10 , 20 etc ) and posting date IN SEL SCREEN OF CO11N
    AFRUD_IMP-BUDAT( POSTING DATE )  CONTAINS VALUE  in debugging mode , hence i m getting the value of posting date
    and in that case check is written in code.  This is the case of full confirmation.
                                 But in case of partial confirmation  i have to give   production order no , operation activity no , *Partial confirmed qty * and posting date , in this case the posting date value changes to 0 in the debug mode ie.
  AFRUD_IMP-BUDAT is showing 0 and hence no calculation can be done base on the date.
      Our requirement is such that if there is a prd order no say X,
then in CO11N if user enters prd no X  , operation activity no 10 , post date say D1
then again for  prd no X  , operation activity no 20 , post date  of activity 20 should not be less than D1
SIMAILARY for  X,  ACTIVITY 30 ,  post date should not less than that of  activity  20. and so on.
    But if partial quantity is mentioned value of  AFRUD_IMP-BUDAT is becoming null.
      If anyone knows about this scenario please share.
  Thanks and regards

Hi, In the T-code Mb31 
The Posting Date which is used  is when entering the document in Financial Accounting or Controlling. The fiscal year and the period for which an update of the accounts specified in the document or cost elements is made, are derived from this posting date.
When entering documents, the system checks whether the posting date entered is allowed by means of the posting period permitted.But this posting date can differ from both the entry date (day of entry into the system) and the document date (day of creation of the original document).This is for the practical purpose .
So its for the Monthly permitted and not for a day or range .
Secondly when you are saying :
"We want this <b>default date to get freeze</b> the moment you enter
the transaction (MB31). If you are opting for second option we want
<u><i><b>some flexibility to change the date as required</b></i></u>."
Both freezing and opting for changes is not possible , either one can occur .
You can freeze/display mode only  the field for the T-code and the document type, but that will not solve your problem .
What i understand from the description is you want to Do GR on A particular date or GR should be allowed after a particular date . <u><b>Please let me know</b></u> if this is the case then there's a way around to do this that is you can do GR and Post on the dates near to your desirable dates .
