      Copy codeSwitch to dark mode

      123456789101112131415161718192021
      {
      "OnFailure": "/SAPAssetManager/Rules/Common/UpdateRequiredFailed.js",
      "OnSuccess": "/ZSAPComponent/Rules/Inventory/Z_PurchaseRequisition/Z_PurchaseRequisitionCreateOnCommit.js", 
      
      "RequiredFields": [
      "PurchasingReq",
      "RequisnItem",
      "ShortText",
      "MatrialListPicker",
      "PlantLstPkr",
      "Quantity",
      "ValuationPrice",
      "DocCategory",
      "DocType"
      ],
      
      "_Type": "Action.Type.CheckRequiredFields",
      "ShowActivityIndicator": true,
      "ActivityIndicatorText" : " " 
      }
      

1. Create a Z_PurchaseRequisitionCreateOnCommit rule to validate the fields and call the commit action.

   1. Use the following code:

      Code Snippet

      Copy codeSwitch to dark mode

      123456789101112131415161718192021222324252627282930
      
      import commonLib from '../../../../SAPAssetManager/Rules/Common/Library/CommonLibrary';
      import Logger from '../../../../SAPAssetManager/Rules/Log/Logger';
      
      export default function Z_PurchaseRequisitionCreateOnCommit(context) {
      let onCreate = commonLib.IsOnCreate(context);
      
      return validateData(context).then(valid => {
      if (valid) {
      if (onCreate) {
      
      let plant = context.getPageProxy().getControl('FormCellContainer').getControl('PlantLstPkr').getValue()[0].ReturnValue;
      commonLib.setStateVariable(context, 'Z_PurchaseRequisitionPlant', plant);
      
      let storageLocation = context.getPageProxy().getControl('FormCellContainer').getControl('StorageLocationPicker').getValue()[0].ReturnValue;
      commonLib.setStateVariable(context, 'Z_PurchaseRequisitionStorageLocation', storageLocation);
      
      return context.executeAction('/ZSAPComponent/Actions/Inventory/Z_PurchaseRequisition/Z_PurchaseRequisitionCreate.action').then(() => {
      return context.executeAction('/SAPAssetManager/Actions/Page/ClosePage.action'); 
      }).catch((error)=>{
      Logger.error('PurchaseRequisition', 'PurchaseRequisition.create error: ${error}');
      });
      } else {
      //Update NOT Supported
      }
      }
      return false; //Validation failed
      })
      }
