FIELD statement in PAI

[Former Member]

Hi I am new to ABAP development.My question is:

How the system comes to know or predict that there is a FIELD statement in PAI event block during the data transport at the beginning of PAI processing?

During the data transport how the system holds the values of fields(without transporting in to ABAP program) mentioned in FIELD keyword?

Controlling the Data Transfer (SAP Library - SAP NetWeaver by Key Capability)

In the above example how system only transfers box4 value?

how system predicts that box1,box2,box3 are specified in the FIELD keyword at the start of PAI processing?

Hi Vamsee,

Whenever system executes the flow logic, it traverse from top to bottom to find the elements that comes under the FIELD statement. Screen contains runtime information and transfers the value automatically. If a element is having FIELD statement then its value is only getting transferred when its corresponding field statement is reached.

As example suggests that FIELD4 is not having FIELD statement so its value gets transferred and available in all the three modules.

Rest of the field's values get transferred when their corresponding FIELD statement gets reached by compiler. Thats why the last module has the all values in their appropriate variables.

Hope it helps.!!!

Thanks,
