Use

System variables have been predefined by SAP. You can use these variables in formulas or, for example, to pass on certain pieces of information to a function module. How the function called by the function module behaves depends on the type of information passed on.

At present, you can use the following system variables:

Features

Variable SY_MODE

You use variable SY_MODE to tell the function module in which mode you currently are the PI sheet. Depending on this information, the function called by the function module is either started in the display or change mode.

You can pass on the following values for SY_MODE:

Variable SY_TEST

You use variable SY_TEST to tell the function module whether you currently are in an active PI sheet or a test PI sheet. Depending on this information, the function called by the function module is either started in the display or change mode.

You can pass on the following values for SY_TEST:

Variable SY_ROW

If you have defined dynamic function calls in a repeated data request (table), you can use variable SY_ROW to tell the function module in which table line you currently are.

Variable SY_VALUE or X

Variable SY_VALUE or X always refer to the value entered immediately before.

Example

If you want to be able to jump to inspection results recording for the inspection point in quality management in the PI sheet, you must use function module COPFX_QM_INSPECTION_RESULT_REC to define a function call.

For the function module to be able to know in which mode the called transaction is to be started, you must use system variables SY_MODE and SY_TEST to pass on the information about the current status of the PI sheet to the function module. In this function module, you use parameters MODE and TEST_FLAG to pass on the variables.

To specify this information in the process instruction, you assign the following characteristics:

Depending on the mode in which you currently are in the PI sheet, the corresponding mode is called in inspection results recording:
