Liquid UI - WS Reference Library

Retryonerror


Purpose

Upon the appearance of an error message, adding delay time option in a loop repeatedly activates the "Enter" button until the error message disappears from the current screen. This is particularly useful in a function following a modifying or complementary transaction, when you call up a further transaction for which the completion of the current transaction is a necessary condition. The system displays an error message until the required modification has been confirmed.

Liquid UI Script

Declare a variable in the esession file to start the delay time in seconds.

DELAY = 20;  // start delay time with 20 seconds
//Add delay time in a loop inside the function
Function:
onscreen 'SAPLIQS0.0100'
   i=0;
   enter("/niw51");
RETRY_DELAY:;      
onerror
   i++;
   delaytime = DELAY*i;
   enter(delaytime);      
   goto RETRY_DELAY;
