What is unpack command

Hi,

Unpacks the packed field f and places it in the field g with leading zeros. If g is too short, it is truncated on the left.

Example

DATA: P_FIELD(2) TYPE P VALUE 103,

C_FIELD(4) TYPE C.

UNPACK P_FIELD TO C_FIELD.

WRITE: / C_FIELD.

Thanks,

Hi,

Unpacks the packed field field1 and places it in the field field2 with leading zeros. If field2 is too short, it is truncated on the left.

Example

DATA: P_FIELD(2) TYPE P VALUE 103,

C_FIELD(4) TYPE C.

UNPACK P_FIELD TO C_FIELD.

P_FIELD: P'103C' --> C_FIELD: C'0103'

Hi Harika ,

Unpack command is used to add leading zeros .

This is usefull because when using many functions / in select statements the value is required in its full length.

An example of this is the function module 'CO2H_PROD_ORDER_READ' in this if u give the value of a valid production order of length 10 , it will execute and give u the result , but when u do the same from a program it will not give u the result the reasonf being that the FM starts to search for a the PO whose lenght is 10.

Now if you use the unpack command the 2 spaces which are blank are added as zeros in the front.

You can also try the same with material number.
