3.4 Custom required SAP fields

Making a custom SAP field required:

• We will use the following standardized functions to check to see if the field is empty. Place these wherever you are loading your functions.

function isBlank(jvar){ 
return(jvar == 'undefined' || jvar == null || jvar == "" || jvar == void 0); 
} 
String.prototype.trim = function() { 
return this.replace(/^\s+|\s+$/g,""); 
} 

• In Designer select the field to become required. Right-click -> Properties.
• Click the "Required" checkbox. This will display required to the user on SAP.
• Use the trim method to remove any whitespace from the variable as follows:
  z_iw51_description = z_iw51_description.trim();
• Use the isBlank function to check if the variable is empty. Use a return statement to stop the process and to alert the user. This goes at the very beginning of your function:

if (isBlank(z_iw51_description)){ 
return("E:Description is required"); 
} 

• Repeat steps 2-5 for each variable you want to make required.
• Save in Designer and all the changes will appear in SAP.
