Note: The BASE64-ENCODE and BASE64-DECODE functions: Use the Base64 Alphabet table as. Returns the maximum length (in bytes) of the result if you were to encode binary data within a byte span with the specified length. A MEMPTR or RAW expression containing the binary data you want to convert. Returns the maximum length (in bytes) of the result if you were to decode base-64 encoded text within a byte span with the specified length. The encoder does not add any line feed (line. The encoded text output is larger than the binary data contained in the input (the operation inflates the data). Uses The Base64 Alphabet as specified in Table 1 of RFC 4648 and RFC 2045 for encoding and decoding operation. If the input is not a multiple of 4, the method will not decode any data.ĮncodeToUtf8(ReadOnlySpan, Span, Int32, Int32, Boolean)Įncodes the span of binary data into UTF-8 encoded text represented as base 64.Įncodes the span of binary data (in-place) into UTF-8 encoded text represented as base 64. The decoded binary output is smaller than the text data contained in the input (the operation deflates the data). If the input is not a multiple of 4, it will decode as much as it can, to the closest multiple of 4.ĭecodes the span of UTF-8 encoded text in base 64 (in-place) into binary data. You may follow the second half from “ Setting up the QR Code font” of my previous blog on how to display QR code on any SAPScript/SmartForms layouts.DecodeFromUtf8(ReadOnlySpan, Span, Int32, Int32, Boolean)ĭecodes the span of UTF-8 encoded text represented as base 64 into binary data. Take the value of export parameter QRCODE_BASE64 and generate the QR code. Once you run the FM with any invoice whose eInvoice has been generated then you will get the output of this FM as shown below. All indices are listed in the Base64 table above. "Should ignore errors in code conversionsĬATCH cx_sy_codepage_converter_init."Should ignore errors in code conversions Only indices determine which characters will be used to encode the data, and only thanks to them you can recover the original data. The subroutine convert_hex_to_str is *&-* Table 1: The Base64 Alphabet Value Encoding Value Encoding Value Encoding. These steps will enable us to successfully decode the base64-encoded. PERFORM convert_hex_to_str USING qrcode_hexstr CHANGING qrcode_string. base32 - Base32 encode/decode data and print to standard output. The encoding and decoding algorithms are simple, but the encoded data are. Split the binary into groups of 8 bits, which correspond to characters in the ASCII table. SELECT SINGLE qr_code FROM edosainv INTO qrcode_hexstr SELECT SINGLE edoc_guid FROM edocument INTO v_guid * have been successfully generated from transaction EDOC_COCKPIT against * For this FM to give QR value result in base64 encoding, XML should *" REFERENCE(QRCODE_HEXSTR) TYPE EDOC_SA_XSTRING Over time, the byte became 8-bit, and the ASCII was extended to 256 characters keeping the first 128 characters intact. I have created a custom FM which takes invoice number as input and gives QR code values in Base64 along with hex and string. First 128 characters in the table above is also known as the 7-bit ASCII table, since it was developed in 1963, when one byte was 7 bits long. You can then use the base64 value obtained in the final step 3 to generate the QR code. The second step mentioned above is just to “see” the value in string. In contrast, the base64 encoding is more often used for raw binary data that is not in human-readable form anyway. Accepts a base-64-encoded string version of a command. RFC 4648 Base-N Encodings October 2006 1. Convert the hexa from EDOSAINV-QR_CODE directly to Base64 using method encode_x_base64 of cl_http_utility instead of converting first to string and then to Base64. Read our practical guide on base64 encoding & decoding techniques. Decodes a base64 string encoded using the standard alphabet according to RFC. Note: You may convert to Base64 is just two steps as well. Selector for the Base 64 Encoding alphabet used for encoding and decoding. The first step in the encoding process is to obtain the binary representation of each ASCII character. The term Base64 originates from a specific MIME content transfer encoding. Convert the string value obtained from 2nd step to Base64 Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation.Get the QR data stored in Hexadecimal value (RAWSTRING) from table EDOSINV.With the data stored in EDOSAINV-QR_CODE you don’t need to worry on how to build and convert data in TLV format. In this blog I will explain how the same can be done directly from data stored in field QR_CODE of table EDOSAINV. I have explained how QR code can be generated in Base64 encoding conforming to Saudi Arabia ZATCA standard in my previous blog.
