Why? I really don't understand.In SAP's official documentation, the transporting clause provides the following explanation:With the modify variant "Modify itab... transporting F1 F2 ..."The task of updating a line of an internal table can be accelerate

ABAP report development instance.Here is an example to illustrate the simple process of developing a report for ABAP. We do not discuss the correctness or rejection of the program. We only care about the compiling process of the program.First, at the beginning of any program, we need to determine the tables that will be used. The procedure we are talking about is to check whether the purchase order has been completed. The following three tables are used: Ekko, Ekpo, and eket. The program starts

When I first started learning ABAP, I was always not very clear about the definition of like/like table of/like line! Write down your understanding for future reference. If this is not the case, please correct me! Data: Begin of itab occurs 0,Col1 type I,Col2 type I,End of itab. * * Internal table and StructureData: itab1a like itab. "defines a structure.Data: i

First of all, the interface in Go is divided into two types, no method declaration and method declaration, the corresponding source code is defined as follows: //有方法声明type iface struct { tab *itab data unsafe.Pointer}//无方法声明type eface struct { _type *_type data unsafe.Pointer} Where data points to the actual value information, _type is the data structure that defines the internal type information, and

into another inner table, use the variant of the INSERT statement. _ To reproduce the content of an inner table entry to another inner table and overwrite the table, use the MOVE statement. COLLECT features let me see the dawn of Enterprise report writing. Sometimes we need to summarize the annual turnover of a region or a customer, so COLLECT is very useful. We don't even need to judge whether this record exists like QAD, SAP has helped you deal with all this! However, by default, COLLECT onl

Now the new syntax supports itab[] This array-like form, but note that if the inner table does not contain a deep struct, itab[1 [2] is not allowed, which is one of the differences between the two-dimensional array.Can only be used in the form of itab[1]-colname, that is, using itab[] generally to return a row of data,

ALV has three color settings: Row, column, and cell. 1. Set the color of the column in The slis_t_fieldcat_alv-emphasize, write the color code you need. Eg: Data: fc type slis_t_fieldcat_alv with header line. FC-tabname = 'itab '. FC-fieldname = 'col '. FC-emphasize = 'c100 '. append FC. 2. row color settings. in the itab to be output, add the color column with the type C (4) to record the required color co

Introduction to the Work Area of the header line of an ABAP internal table From http://zhouwubin.blogbus.com/logs/14351256.html When I first learned ABAP and iternal table, I felt a mess.I don't know what work area is, what header line is, and what occurs is.I finally figured it out today (I am still too weak... BS)So record it... save yourself and forget it later... First, use the types keyword to define the type of a row as follows:Types: Begin of line,Field1 type I,Field2 type I,End o

. Therefore, it takes longer to insert data to a standard table than to insert data to a standard table. Therefore, select a key as much as possible to operate the sorting table.Definition method: types/data: Like/type sorted table.2. hashed table: You can operate a hash table only with the key you defined, but not with the index. Therefore, a hash table must define a unique key. Note: All statements about using index to operate a table cannot be used to operate a hash table. For example, sort o

[From] http://blog.csdn.net/hackai886/article/details/7935366 In SAP, table control is one of the most widely used controls in screen. It can edit multiple rows of data.To put it simply, table control is a set of screen elements that appear repeatedly on the screen. This is the difference between table control and normal screen elements.If we define an internal table as itab for a table control, the working area is wa. In PbO, the system will take a l
