Set createnonmissingblk on/off issue

Question

EXAMPLE:
four dimensions in outline:
account (dense) (members: A1,A2)
time(dense) (member: T1,T2)
entity (sparse) (member: E1,E2)
product(sparse) (member:P1,P2)
need to create blocks to enter data, BR like that:
FIX("E1")
  SET CREATENONMISSINGBLK ON;
  "P1"=1;
   CLEARDATA "P1";
  SET CREATENONMISSINGBLK OFF;
ENDFIX;
FIX("E1","A1","A2","T1","T2")
"P1"=100;
ENDFIX;
QUESTION:
"P1"=100 cannot be set to Essbase in the above BR, only if I delete the syntax:"SET CREATENONMISSINGBLK OFF;" then I can set 100 to "P1".
WAHT I THINK:
with the blow script,
FIX("E1")
SET CREATENONMISSINGBLK ON;
  "P1"=1;
   CLEARDATA "P1";
I have already make the block P1->E1 an existing block, then my "SET CREATENONMISSINGBLK OFF;" does not effect the existing block. but why cannot me add "SET CREATENONMISSINGBLK OFF;"?? I don't understand.

Answer 1

FIX("E1")
  SET CREATENONMISSINGBLK ON;
  "P1"=1;
   CLEARDATA "P1";
  SET CREATENONMISSINGBLK OFF;
ENDFIX;
It is because of CLEARDATA, HERE CLEAR DATA is removing block!!!
