User Decimal Format Validation

[Benjamin Dasari]

Purpose:
Validate the user entry decimal format by checking with SAP decimal format.

Liquid UI Code:

// SAPLSMTR_NAVIGATION.E0100.sjs

// Read User Decimal Format Defaults
if(!READDEFAULTS){
   call('BAPI_USER_GET_DETAIL',{'IN.USERNAME':'&V[_user]','OUT.DEFAULTS':'userDefaults'});
   USERDECIMALFORMAT = userDefaults.substring(28,29);
   READDEFAULTS = true;
}

// Remove blank spaces
String.prototype.trim=function(){return this.replace(/^\s+|\s+$/g,'');}

// Function to check if the string value is blank
function isBlank(jvar){
   if(typeof jvar == 'string') {
      jvar = jvar.trim();
   }
   if(typeof jvar == 'undefined') {
      jvar = '';
   }
   return(jvar == 'undefined' || jvar == undefined || jvar == null || jvar == "" || jvar == void 0);
}

// Function converts the user decimal format in SAP to a general decimal format (xxxxxx.xx)
function decimalNotationFormat(numberFormat,number,nDec){
   var str = "";

   if(nDec == void 0)   // Default for number of decimal places
      nDec = 2;
      
   switch(numberFormat)
   {
   case 'X':
      {
         str = number.replace(/\,/g, '');      // Replace , with nothing
      }
      break;
   case 'Y':
      {
         str = number.replace(/\s+/g,'');      // Remove Blank Spaces
         str = str.replace(/\,/g, '.');         // Replace , with .
      }
      break;
   default:
      {
         str = number.replace(/\./g, '');      // Replace . with nothing
         str = str.replace(/\,/g, '.');         // Replace , with .
      }
      break;
   }
   return parseFloat(str.trim()).toFixed(3);
}

// Function converts the general decimal format to user decimal format in SAP
function userSAPDecimalFormat(nStr,nSeparator){
   var str = nStr.split('.');
    var offset = str[0].length % 3;

   if(nSeparator == ' ')
      str[0] = str[0].substring(0, offset) + str[0].substring(offset).replace(/([0-9]{3})/g, ".$1");
   if(nSeparator == 'X')
      str[0] = str[0].substring(0, offset) + str[0].substring(offset).replace(/([0-9]{3})/g, ",$1");
   if(nSeparator == 'Y')
      str[0] = str[0].substring(0, offset) + str[0].substring(offset).replace(/([0-9]{3})/g, " $1");
   
   if(offset == 0)
      str[0] = str[0].substring(1,str[0].length);

   if(nSeparator == 'Y' || nSeparator == ' ') {
      return str.join(',');
   } else {
      return str.join('.');
   }      
}   

// Function to check and convert user entry for decimal format
function changeUserFormat(){
   if(isBlank(z_val)){
      return('E: Please enter value');
   }
   z_val = decimalNotationFormat(USERDECIMALFORMAT,z_val.toString(),3);
   z_tmp = userSAPDecimalFormat(z_val,USERDECIMALFORMAT);
   set('V[z_val_userformat]','&V[z_tmp]');
}
 
// User Interface
clearscreen();
inputfield([1,1], "Enter Decimal Value", [1,22], {"name":"z_val", "size":15});
inputfield([2,1], "User Format", [2,22], {"name":"z_val_userformat", "size":15, "readonly":true});
