Initial data load and Delta load


I'm wondering about the Initial Data Load and Delta Load.

While learning Product Substitution process, i saw a description that Condition records can be loaded to CRM with an initial data load or a delta load.

I think these are the way to transfer master data.

Could you tell me what they are ?

Hello Seunghyeok,

1. The destination of the delta load is object-based. You can check the initial load destination of the object in "initial flow contexts" tab of t-code R3AC1. For example, the initial load of object BUPA_MAIN can be both run from ECC to CRM and from CRM to ECC. However, the initial load of object CUSTOMER_MAIN can be only run from ECC to CRM. The destination of the delta load is the same with initial load.

2. Your understanding is not correct. The first load is indeed called the "initial load" and the subsequent load (called "delta load") then automaticaly happen everytime some changes happen.

You also have request load, using which you can download range of materials/BPs which are missing or needs to be updated.

Additionally, delta load is not available for all objects. It is available for master and transactional data (the objects in R3AC1), while on other hand for customazing data (the objects in R3AC3) you should always use initial load or request load.

Please read more documentation regarding the data exchange between CRM and ECC for better understanding, such as:


Best regards,
