RAP 7: Draft functionality in RAP

• In this post will show you how to create Draft functionality in RAP Application.

• Step 1: Open the Interface view behavior definition and add key workd as with Drft , draft table and create draft table, total etag, with draft into create  as show in below:
• 
  
  
  

• Interface view Behavior definition code:

• managed;

  strict ( 2 );

  with draft;

  
  

  define behavior for ZR_SALESORDER_HEAD_M alias Header

  implementation in class zbp_r_salesorder_head_m unique

  persistent table zms_sales_head

  draft table zdt_sales_head

  lock master

  total etag LastChangedAt

  authorization master ( instance )

  etag master LastChangedAt

  {

  create ( authorization : global );

  update;

  delete;

  field ( readonly ) SalesOrder, Ernam, LastChangedAt;

  association _Item { create; with draft; }

  
  

  draft action Activate optimized;

  draft determine action Prepare;

  draft action Edit;

  draft action Resume;

  draft action Discard;

  
  

  mapping for zms_sales_head //db table name

  {

  
  

  //CDS View field //DB Table field name

  SalesOrder = vbeln;

  DocumentDate = audat;

  OrderType = auart;

  SalesOrganization = vkorg;

  DistributionChannel = vtweg;

  Division = spart;

  Erdat = erdat;

  Erzet = erzet;

  Ernam = ernam;

  LastChangedAt = lastchanged;

  }

  }

  define behavior for ZI_SALESORDER_ITEM_M alias Item

  implementation in class zbp_i_salesorder_item_m unique

  persistent table zms_sales_item

  draft table zdt_sales_item

  lock dependent by _Head

  authorization dependent by _Head

  etag dependent by _Head

  {

  update;

  delete;

  field ( readonly ) SalesOrder, Item;

  
  

  association _Head {with draft;}

  mapping for zms_sales_item //db table name

  {

  
  

  //CDS View field //DB Table field name

  SalesOrder = vbeln;

  Item = posnr;

  Material = matnr;

  MaterialDescription = arktx;

  Quantity = kwmeng;

  Unit = vrkme;

  Netpr = netpr;

  Currency = waerk;

  }

  }

• Step 2: Creation of draft table: Write the “draft table <Table Name> and place the cursor on the table name and quick the shortcut as “Clrl+Shift+1, it shows shortcut popup, click on Create table

• Header Draft table
• 
  
  
  

• Item Draft table
• 
  
  
  

• Step 3: Open the projection view behavior definition and write brloe code
• 
  
  
  

• Projection view Behavior definition code:

• projection;

  strict ( 2 );

  use draft;

  
  

  define behavior for ZC_SALESORDER_HEAD_M alias Header

  use etag

  {

  use create;

  use update;

  use delete;

  use association _Item { create; with draft; }

  
  

  use action Edit;

  use action Activate;

  use action Discard;

  use action Prepare;

  use action Resume;

  }

  
  

  define behavior for ZC_SALESORDER_ITEM_M alias Item

  use etag

  {

  use update;

  use delete;

  
  

  use association _Head{ with draft; }

  }

• Step 4: Output:
