ABAP code - General question

[Former Member]

Hi Guys,

What is the difference between the following statements? In what scenarios should we use these?

a. CREATE DATA data_ref LIKE LINE OF xth_data.

ASSIGN data_ref->* TO <ls_data>.

b. LOOP AT xth_data ASSIGNING <ls_data>.

c. LOOP AT xth_data INTO <ls_data>.

Hello Maha,

Thanks for the documents. One of the document (Cyanard's BPS programming document) was informative to some extent.Still, nothing was mentioned about the differences between the 3 statements I mentioned about. Are there any How-To guides or links that can explain these concepts properly.

Thank You.

a. You are creating a variable data_ref which is a workarea of the type xth_data

and assigning that structure type to the field symbol <ls_data>

b. the field Symbol <ls_data> does not need to be assigned to any datatype

It will get assigned to the structure of xth_data

c. It is assumed that your field-symbol <ls_data> has already been assigned to the xth_data type

this code simply loops into the table

note that if your field symbol is not assigned as yet, it will result in a GETWA_NOT_ASSIGNED short dump
