Org unit not visible in the search

Hi All,

In the master data maintenance of the organization management , we have created an sales organization unit (O 50000XXX).

Function and attribute values for sales scenario has been maintained.

Object permitted in determination check box also checked.

while assigning the pricing procedure determination for the sales org (O 50000XXX) we are not able to find the sales org in the F4 search help.

When we are trying to key in it manually it is giving an error msg 'Sales Office O 50000XXX not available'.

Please suggest any inputs.

Thanks

Syam
