Validate SAP screen elements using "isValid" and "isVisible" options

[Benjamin Dasari]

Purpose: To check if a SAP screen element exists and is visible or not. Both the options return true or false.

isValid - Can be used to check if a SAP screen element exists or not, i.e., if the control is sent from SAP even though it is not visible on the screen.
Syntax:
if(<"F[GR/GI Slip No.]">.isValid)      // Check if the field exists
     set("V[z_migo_grgislipnum]","X");     


isVisible - Can be used to check if a SAP screen element is visible or not on SAPgui.
Syntax:
if(<"F[GR/GI Slip No.]">.isVisible)   // Check if the field is appears on SAPgui
      set("F[GR/GI Slip No.]", " ");     // Set it to blank

Example-
SAP R/3 - ZEUS [Internal to Synactive]
Inputfield - "GR/GI Slip No."
Transactions MIGO and Z_MIGO for Goods Issue. This field is valid on both the transactions, however only visible in MIGO and not Z_MIGO.
